For the record, there's no reason to call a revolver DA/SA. It's redundant (like .38/.357) and unnecessary to differentiate from DAO (double action only).

For the record, DA/SA and DAO aren't redundant (nor are .38/.357). Double Action Only revolvers have no hammer spur or SA sear, so the user doesn't have the option of cocking the hammer and shooting SA. To many, the difference matters quite a bit.
